of Newport, in the county Iof Newport and State' ofRhode Island, have invented a new and Improved Hydrocarbon Burner, of which the following `ay full,l clear, and

The invention relatest to hydrocarbon burners suchas vshownan'd described in the Letters'Pat'ent of the United States, No. granted,`May 25, 1920, to Karl A.

The object ofthe present inventionis Ato vprovide a new andv improved hydrocarbon burner arrangedf to `Aproduce a thorough atomizing of crude oil or other hydrocarbon y fuel and ,to insure the formation, of an inti-I mate mixture of vthe atomized fuel and air with a View to produce a practically complete Another object is to spread the flame in the combustionfchamber to insure a 'uniform heating of the furnace or other apparatus to which v the hydrocarbon burneris applied.

Another object is to permitof yaccurately regulating the inflowof the air to be mixed with the atomized fuel.

. Another object istoy providea hydrocarbon burnerwhich'is simple and durable in construction and arranged to readily with'.

``Figure is a` longitudinal central section lof a modified form o ffthe same.

Into thec'ombustion chamber-10 vof a furnace or other apparatus projects a revoluble vcup-shaped atomizer 11 provided at its rear end witha hub 12 journ'aled in a bearing13 formed centrally on-a spherical wall 14 of A"an a-ir inlet casing 15 attached to the front lwall 1G o'f thefurnace or other apparatus.

The hub 12 ofthe cup-shaped atomizer 11 is vsecured'ona hollow shaft 20 journaled in a bearingl 21 attached to or formed on a bracket r 22-pr'eferably` mountedfon the air inlet casing 15. The shaft y20V is connected by a coupling 23with the shaft 24 of an electric F o r other motor 25 of any approved construction and likewise mounted on the bracket 22.

'isrunningarotary motion is given to the Into the cup-shaped atomizer 11 discharges a liquidl fuel supplyvpipe 30y extending through the hollow shafts 20 and 24 and connecting withy a supply vpipe 81 leading *from a tanker other reservoir containing crude oil o r other liquid fuel. Theamount lof liquid fuel passing tothe pipe 30 is controlled by a suitable needle valve 32' arranged -on a fixture 33 connecting the pipes 30 vand l'with each other. 7 1

The atomizer 11 is' preferably made in the form-of a cylindrical c up provided with a 'conical recess `40 having its base end at the forward end of the' cup, vand into the rear apex end ofr this recess '40 discharges the "liquid fuel supplyv pipe 80.` The' conical vrecess `4O`has its wall 41 preferably instep form, as'shown in Figure 1, lto insure a vthorough breaking up `or' dividing of the liquid fuell into minute vparticles a discharged into the combustion chamber from the front end ofthe recess,- andI owing to the conical shape given tothe recess 40 the atomized fuel is spread outward within the combustion chamber 10. The' peripheral face of the atomizer 11vis preferably provided with al front'and a rear set of impeller blades 42 and 43 set in staggeredrelation and with tlierear blades v43 preferably set vat a steeper angle. i When the cup-shaped atomizer is started and liquid fuel passes into the recess 40 then this'fuel Ais cut upA by coming into contact with the steps o'f therecess wall, and

6. In a hydrocarbon burner, a revoluble` cup-shaped atomizer having a conical recess into the rear apex end `of which passes the liquid fuel to be atomized, the said recess having a step Wall and front and rear sets of impeller blades arranged on the peripheral surface of the atomizer.

7. In a hydrocarbon burner, a revoluble atomizer having a cylindrical periphery and a conical recess, the base of which is at the mouth of the atomizer to spread the atomized fuel in front of the atomizer, parallel series of impeller blades on the exterior peripheralI surface of the atomizer for producing a current of air and projecting the same into the said spread atomized fuel at an angle in front of the atomizer, and adjustable air admission means for admitting air to the combustion chamber in which the hydrocarbon burner is located. v

8. In a hydrocarbon burner, a revoluble atomizer having a conical recess, the base of which is at the mouth of the atomizer to spread the atomized fuel infront of the combined nozzle and atomizer, a plurality of circular series of impeller blades on the exterior peripheral surface of the atomizer for producing a current of air and projecting the same into the said spread atomized fuel in front of the atomizer, and a liquid fuel feed pipe arranged centrally in the said atomizer and discharging centrally into the said conical recess at the apex endy thereof.

9. In a. hydrocarbon burner, a revoluble atomizer, having a conical recess, the base of which is at the mouth of the atomizer to spread the atomized fuel in front of the atomizer, impeller blades on the exterior' peripheral surface of the atomizer for producing a current of air and projecting the same into the said spread atomized fuel in front of the atomizer, and a forced draft propeller Wheel independent of the impeller blades, rotating With the said atomizer at the rear thereof.

10. In a hydrocarbon burner, a revoluble atomizer having a conical recess, the base of which is at the mouth of the atomizer to vspread the atomized fuel in front of the atomizer, front and rear rows of impeller blades on the. exterior peripheral surface of the atomizer for producing a current of air and projecting the same into the said spread atomized fuel in front of the atomizer, a forced draft propeller wheel rotating with the said atomizer at the rear thereof, and forced air admission means intermediate the said propeller and the atomizer.

11. In a hydrocarbon burner, a revoluble atomizer having a conical recess, the base of which is at the mouth of the atomizer to spread the atomized fuel in front of the atomizer, parallel rows of impeller blades on the exterior peripheral surface of the atomizer for producing a current of air and projectin the same into the said spread atomized fuel in front of the atomizer, a forced draft propeller Wheel rotating with the said atomizer at the rear thereof, forced air admission means intermediate the said propeller and the atomizer, and manually controlled regulating means for the said forced air admission means to regulate the amount of air passing to the combustion chamber in which the hydrocarbon burner is located.
